Seeds per pack: 20

Germination: Start these seeds right away to preserve viability, no matter the time of year. Sow the seeds just under the surface of a sterile seed-start mix, and water in. Leave them at room temperature for 4 weeks. If no growth appears a cold treatment may be required to break dormancy. Then cover them with plastic and place in a fridge for 6 weeks. Be sure they stay moist. After the cold stratification period they are then brought back to room temperature for them to germinate. Germination is in 14-45 days after the warming period.
